UIImagePickerController 被解雇时使用 UITabbarcontroller 获取带有应用程序名称的红条答案

【问题标题】：UIImagePickerController when dismissed getting redbar with app name using UITabbarcontrollerUIImagePickerController 被解雇时使用 UITabbarcontroller 获取带有应用程序名称的红条

【问题描述】：

我正在使用 UIImagePickerController 录制视频并拍照，编辑视频并将其保存到文件中。关闭 UIImagePickerController 时，状态栏会闪烁红色并消失，有时我的标签栏会向下移动。无法理解为什么会发生这种情况。问题出在哪里。

我想避免这种情况。我注意到这一点从 iOS8.1、iOS8、iOS7.1 等开始逐渐减少

标签栏向下移动一段时间（意味着随机）。

当我在服务器中录制视频和上传或使用 uiimagepickerviewcontreller 中的取消按钮时，为什么会出现钢筋。 .为什么我拍照的时候它不进来，为什么它不是每次都来。

    -(void)mediaAction{

/// calling action sheet action 
        }

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

    //setting for image
    cameraUI = [[UIImagePickerController alloc] init];
    cameraUI.delegate = self;


    //Get the name of the current pressed button
    NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex];

    if ([buttonTitle isEqualToString:@"Record a Video"]) {
        mediachecker=@"video";
        cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
        cameraUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
        cameraUI.allowsEditing = NO;
        [self presentViewController:cameraUI animated:YES completion:nil];

    }
    if ([buttonTitle isEqualToString:@"Upload from Gallery"]) {
        //NSLog(@"ChooseFromGallery");
        mediachecker=@"video";
        cameraUI.allowsEditing = YES;
        cameraUI.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
        cameraUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
        [self presentViewController:cameraUI animated:YES completion:NULL];

    }

    if ([buttonTitle isEqualToString:@"Click a Picture"]) {

        mediachecker=@"photo";
        cameraUI.allowsEditing=YES;
        cameraUI.sourceType=UIImagePickerControllerSourceTypeCamera;
        [self presentViewController:cameraUI animated:YES completion:NULL];
        //NSLog(@"UseCamera");

    }
    if ([buttonTitle isEqualToString:@"Photo Library"]) {
        //NSLog(@"UseGallery");
        mediachecker=@"photo";
        cameraUI.allowsEditing=YES;
        cameraUI.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentViewController:cameraUI animated:YES completion:NULL];

    }

    if ([buttonTitle isEqualToString:@"Cancel"]) {
    }

}  



 - (void) imagePickerController: (UIImagePickerController *) picker
             didFinishPickingMediaWithInfo: (NSDictionary *) info {

                [picker dismissViewControllerAnimated:YES completion:nil];

            //getting file here; and uploading 
}


- (void) imagePickerControllerDidCancel: (UIImagePickerController *) picker {


[[picker presentingViewController] dismissViewControllerAnimated:YES completion:nil];
            //dissming here; 

            }

我已经参考了这些链接 Redbar Noticed when dismissing UIImagePickerController

IPhone - After dismissing Modal View Controller - gap is left at top of page

但仍然遇到同样的问题。如何解决这个问题。

【问题讨论】：

您是否在标签栏添加了一些边缘插图？
不，我没有添加

标签： ios objective-c uinavigationcontroller uitabbarcontroller uiimagepickercontroller

【解决方案1】：

我在拍摄视频时遇到了 UIImagePickerViewController 关闭的相同问题：不要递归引用 Stack Overflow 链接，但这为我解决了：

尝试：“您应该在 .plist 中将“基于控制器的状态栏外观”值设置为 YES”

UIImagePickerController messing tabbar frame when dismissing

不知道为什么那个答案引用了这个，这里没有回答。
